Welcome to Ham Radio Outlet, the largest ham radio dealership in the world.
The National HRO was a valve-based (tube) shortwave general coverage communications receiver, manufactured by the National Radio Company (National) in Malden (Massachusetts, USA) from 1935 onwards. The receiver was intended for military and amateur use and became very popular for intercept work during WWII .
The original published story for the origin of the HRO designation related that all of National's inter-departmental paperwork for the receiver project was stamped "H.R.O." which stood for "Hellva Rush Order" since the time table for the receiver development was a "rush order" type of project.
The original National HRO was a 9-tube HF (shortwave) general coverage communications receiver manufactured by the National Radio Company of Malden, Massachusetts, United States. James Millen (amateur radio call sign W1HRX) in Massachusetts was in charge of the mechanical design.
